Black cherry aphid

Description, Biology, Life Cycle, Damage, Common Names, Images


[R]Description
- Apterous adult: 2 mm long; globe-shaped; dark brown to shiny black.

[R]Biology
- A heteroecious species: primary hosts are cherry and wild cherry (Prunus cerasus and P. avium); secondary hosts are Galium, Veronica, Asperula.
- These aphids overwinter in the egg stage, eggs having been deposited on trunks, branches or buds. Fundatrices emerge in March-April. Several generations follow each other, feeding on the tip of shoots of cherry or on the underside of leaves, causing the leaves to form compact bundles visited by ants.

[R]Life Cycle
- Winged aphids emerge in June-July, migrating to secondary hosts on which they will breed. A return migration to cherry takes place in the autumn and winter eggs are eventually laid.

[R]Damage
This species freauently causes damage. Depredations occur at the maturation period of cherry, attacks being especially severe on young trees. Leaves curl up, become scabby and form dense bundles (*) . The presence of honeydew causes a scorching of leaves which moreover become dry.
